Capacitively coupled electrical field in the treatment of a leg fracture after total knee replacement.

Electrical stimulation has been used as treatment for nonunions of fractures since the early 1950s, with a reported success rate of 80-85%. We report a case of nonunion of a tibial fracture below a revised total knee prosthesis treated with a capacitively coupled electrical field. After 3 months of treatment, consolidation of this difficult fracture was evident with abundant callus formation.
